If that smell was like rotten eggs, then it would be your catalytic converter, if yours is blocked up it's forcing the exhaust to go out through a seam or crack in the exhaust or through a hole burned into the side of the converter. Either way you should have your exhaust checked out, fumes getting into the cabin area can be a real killer.
